I have always just donated my old clothes but since having kids, it made sense to try to sell them and get some of that money back! I don't have the time to sell it myself. This is where Thredup does everything. I sort through my two kids clothes as well as mine and my husbands. I order a bag and stuff it full. I send it back, free of charge. A couple of weeks later, they let you know how much money you get for the clothes and they donate the rest of the bag. Barely any effort on my part. Over the past 2 years I have probably gotten $1,000. I generally just spend the money on their website, since the kids always need new sizes. The clothes are of high quality. You can barely tell they were already used. I love being able to get $$ for clothes I would have just donated! It's like free money. And it's so simple!
